Homework Statement
The Earth has a radius of approximately 6400 km. If an object could orbit the Earth just at its surface, how fast would it have to travel?
Homework Equations
C = 2πr; ac=v2/r; Fc=mv2/r
The Attempt at a Solution
Circumference = 12800π. I tried to solve for the rate by d = r x t (86400s = 24 hours) but my answer is very small.
